Figure 2

Phylogenetic tree of dnd operons from Enterobacteriaceae . Asterisk (*) indicates that the genome contains two copies of dnd operons. Different alphabets (a, b, cI, cII, d, e, f) depict the subgroups based on the immediate genetic environment. Colored genome strain codes facilitate visualization. Maximum likelihood (ML) method was used to construct the phylogenetic tree using MEGA5. Bootstrap confidence values greater than 50% are shown at branches. Nodes with less than 50% bootstrap value are collapsed.
